CHEMICAL SHOT-FIBER.

Application tiled June 3,

To all whom it may concern:

Be it known that l. Joux Down, a citizen of the United States, aml a resident of Chicopee. in the county ot Crawford and State of Kansas, have invented a ney and improved Chemical Shot-Filer, of which the following is a `full,- scription.

The invention. chemical shot lirers for settingoli' blasts and otherexplosivc charges, and has in view ya device ot' this character which will ignite the charge with certainty only after a predetermined length ot' time. and thus operator ample opportunity to move out of range before the explosion occurs.

To this end the invention consists of a shell from which a tuse extends to be connected to the charge, and a container having a liquid, the liquid adapted to pass through the container after a predetermined period,

and the container arranged for the liquid to drop into the shellai'te'r passing therethrough, with the shell having a material tlierein igniting by the addition ot' the said liquid. ,y

Reference is to be ing drawings forming had to the aceon'ipanyapart of this specitication, in which similar characters of relerence indicate correspondingl parts in both the views.

Figure 1 is a. perspective view of a chemical shot tirer constructed in accordance with my invention; and Fig. 2 is i longitudinal vertical central section of the. same.

The invention as specifically set forth comprises a shell 5, from which a tue-1e (3 extends. and filled with a material or compound 7, and a container 8 having a liquid 9 which is adapted to pass therethrough after a certain interval of time, the containerl being arranged so that the liquid will fall into the shell after the liquid passes through the bottom thereof, the compound 7 being such as /to produce a flame when brought together. For this purpose l preterably malte the compound 7 ot' potassium chlorate and sugar, and for the 'liquid 9 l use sulfuric acid. The shell 5 is ordinarily made of paper heavily paratlined, which makes this part ot the shot tirer waterproof. The fuse, which, in the useof the tirer is passed within the charge to he exploded, ordinarily extends from the compound 7 within the shell through a cork l0. closing the outer end of the shell.

l The container 8 is shown to l most of a number of capsules, l sule 11 ot' which extends through the side of the shell well into the compound 7, and has tel escoped therein the lower portion or section ot1 the'capsule 12, which in turn likewise receives the container eapsule, the upper section of the outer or charge capsule ll-titting over the capsule section 12- and covering it and thecontainer. The capsules are of gelatin or some material through which the acid will eat after a predetermined time, thebotltom wall of the several capsules being spaced a substantial distance a )art so that the acid will successively pass ,rom one capsule to the next capsule below and finally enter the potassium chloratc and sugar. By` multiplying,r the capsules, thc time required for the acid to enter the material 7 may be lengthcned as to any suitable period. Ordinarily, however, three capsules or capsule sections' will under most circumstances be found Sullicient.

In the manufacture of the cart-ridge, it is preferably made complete,`with the exception ot the addition of the acid, this being added by a droppcr or other device after the cartridge isotherwise in position an readiness tor .exploding the charge. By the arrangement off-the acid at the outside of the shell removed from the potassium chlo-` rate` and sugar, there is no danger of the two being brought together prematurely.

Having thus, described my invention, I claim as new and desire to secure by Letters Patent:

l. ln a chemical shot tirer, a shell, a container having a liquid, the liquid adapted to pass through the container after a predetermined period, and the container arran re for` the liquid to drop into the shell a ter passing therethrough, and a material Within the shell igniting by the addition of the said liquid. y

2'. In a chemicalA shotx tirer, a shell, a cog., f tainer arranged at the outside of the Sher and having a liquid, the liquid adapted to consume the container after a predetermined period, and the container arranged for the liquid to drop into therethrough. and a producing a flame said liquid.

3. 'n a chemical shot tirer, a shell conl taining potassium chlorate and sugar, and a l sulfuric acid container, the container of a be the innerv the outerc'apthe shell after passing` vpotassium chlorate material through which the acid is adapted to pass after a predetermined period, and arranged so that the acid will drop into and sugar atterpassi'ng through the container.

4. In a chemical shot lirer, a shell,v a chemical compound Within the shell, a fuse extending from the compound to the outside of the shell, and a capsule acid container supported at the outside of the shell of a material through which the acid is adapted to pass after a predetermined period, and arranged for the acid to drop within the said compound within the shell after passing therethrough.

5. In a cliemicahshot firer, a shell contamingachemical compound, a fuse. leadi ing from-the said compound to the outside shell of the shell, and a container arranged at the outside and above the shell, having a liquid, the said liquid adapted to penetrate the shell after a predetermined vtime and cause ignition when added to the said compound, with the container arranged for the liquid to drop into the shell'after the liquid `passes through the container.

6. In a chemical shot tirer, a paratlined containing potassium chlorate and -two subscribing Witnesses.

sugar, a fuse leading from the potassium chlo'rate and sugar to the outside of the shell, a capsule exten in chlorate to the o tside and above the shell, a. capsule container arranged wit-hin the first-named capsule, and an acid within the capsule container, producing ignition when added to the otassium clilorate, and adapted to successively penetrate the said capsules after a predetermined period.

In a chemical shot tirer, a shell having a compound, a succession of capsules telescoped one within the other, with the bottoms of the capsules arranged substantially apart, with the lower capsule extending upwardly through the shell in a position to discharge into the compound, and the upper capsulecontaining an acid adapted to successively penetrate the capsules after a predetermined. time and cause ignition when added to the said compound.

In testimony whereof I have signed my name. to this specification in the J OHNrDOWD.'
